MAX22344BAAP+T

Digital Isolators Overview

The MAX22344BAAP+T is a four-channel digital isolator utilizing capacitive coupling technology, housed in a 20-SSOP package. It provides an isolation voltage of 3750 Vrms and supports data rates up to 25 Mbps for standard operation, with specific variants supporting 200 Mb/s. The device operates on supply voltages ranging from 1.71V to 5.5V and features a typical common-mode transient immunity (CMTI) of 50 kV/µs. Designed for robust performance, it functions within a temperature range of -40°C to 125°C.

Digital Isolators Feature Summary

• Four-channel unidirectional signal isolation using capacitive coupling technology

Digital Isolators Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and speed grade. Ensure the 20-SSOP package matches your PCB footprint requirements. Confirm operating temperature ratings align with your environmental specifications before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when multiple isolated channels are required in a compact surface-mount package. Consider the 25 Mbps or 200 Mbps speed variant based on your system's bandwidth needs. Verify that the 1.71V to 5.5V supply range accommodates your logic levels and power constraints.

Digital Isolators Part Context

This part belongs to the Maxim Integrated digital isolator family, now under Analog Devices. It replaces older optocoupler solutions by offering higher speed and lower power consumption. The BAAP+ designation indicates a specific lead-free and RoHS-compliant version within the broader MAX22344 series.

Digital Isolators Replacement Considerations

Consult official cross-reference guides for direct replacements. Generic equivalents may not match the specific CMTI or propagation delay characteristics. Verify pin compatibility if substituting with other quad-channel isolators.
